Haruhiko Kuroda, governor of the Bank of Japan (BOJ), speaks during a news conference at the central bank's headquarters in Tokyo, Japan, on Thursday, June 16, 2016. The BOJ refrained from expanding monetary stimulus ahead of the U.K. vote on Brexit next week that could roil global markets, and before a domestic election in which the political opposition has made the bank's negative interest-rate policy an issue.
